Ask AI: 90 WORDS CONCUSSION THE COMPARISON OF DNA CONFORMATION.

DNA conformation refers to the various shapes that double-stranded DNA can adopt. The primary conformations are A-DNA, B-DNA, and Z-DNA. B-DNA is the most common form under physiological conditions, characterized by a right-handed helix with about 10.5 base pairs per turn. A-DNA is a right-handed helix, more compact than B-DNA, with 11 base pairs per turn, usually forming under dehydrating conditions. Z-DNA is a left-handed helix with 12 base pairs per turn and occurs in high salt concentrations or during biological processes like transcription. These conformations highlight DNA's structural versatility and functional adaptability.
